CD’s enjoyment of the beauty of the tropics is worth all the misery of seasickness. His mail gave him great pleasure. For two weeks he will visit a large estate in the country, and on return live at Botofogo for some weeks, collecting and learning to know the tropics.

His trip to the interior was full of interest, but exhausting physically. Expects to stay at least a fortnight at Botofogo, because the Beagle returns to Bahia to correct a difference in the longitude measurements. Writes of his companions, of FitzRoy, and of his journal – which he has sent home.

During the past two months CD has been lucky with fossil bones, and he is also finding new specimens of living animals.

He describes an ostrich hunt.

Has received several letters from home.

He enjoys Buenos Aires and admires the señoritas. Tierra del Fuego is next.
